Solid-state imaging device having an amplifying means in the matrix arrangement of picture elements
United States Patent 04809075

A solid-state imaging device is constructed by integrating a plurality of face plate elements of an imager in the shape of a matrix on a semiconductor substrate. The face plate elements are formed of photodiodes, in which charges corresponding to incident light are accumulated. The charges are converted into currents or voltages by a plurality of amplifying means disposed in the matrix and which are provided adjacent to the photodiodes. The currents or the voltages obtained through conversion are delivered out of the matrix through signal lines. To the signal lines a correlated double sampling circuit is connected, and this curcuit detects a difference in outputs of the amplifying means between a case when the charges of the photodiodes are not present in the input portions of the amplifying means and a case when they are present therein.
